Sound not working in Flash? Here's a possible fix.

Here's the symptom: your sound works fine, except in Flash. You've tried multiple browsers and Flash sound doesn't work in any of them.

The problem is that you're using PulseAudio as a sound engine and sometimes Flash doesn't work well with it.

To fix this, remove the libpulse0 package. As root:

yast --remove libpulse0

When I did this, it ended up removing MPlayer due to dependecies. I reinstalled MPlayer from the repositories which brought back one PulseAudio package, but sound still worked in Flash.
